JOHN KASMEIER, OF FLORENCE, ALABAMA.

DELlNTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 691,272, dated January14, 1902.

Application filed June 7, 1900.

To allwhom, it may concern:

Be it known that I, JOHN KASMEIER, a citizen of the United States, residing at Florence, in the county of Lauderdale and State of Alabama, have invented a new and useful Delinting-Machine, of which the following is a specification.

My invention relates to machines for treating cotton-seed, and 'particularly to that class of machines known as delinters, adapted for the separation of the lint from the seed.

One object of my invention is to effect improvements in the means for delinting the cotton-seeds.

Another object of my invention is to combine with the delinting-brush spurred retaining-rollers which serve in coacting with the delinting-brush to rotate the cotton-seeds during the delinting process, and thereby expose all the surfaces thereof to the action of the delinting-brush.

Another object of my invention is to combine with the delinting-brush and the retaining-rollers retaining-bars to prevent the cotton-seeds from moving from the surface of the delinting-brush at the points between the retaining -rollers and to vprovide said bars with brushes which coact with the retainingrollers.

With these and other objects in view my invention consists in the peculiar construction and combination of devices hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure lis a sectional view of the delintingmachine constructed in accordance with my invent-ion. Fig. 2 is a side elevation of one side of my improved delint-ing-machine. Fig. 3 is a similar view of the reverse side thereof. Figs. 4 and 5 are detail views.

In the embodiment of my invention I provide a cylindrical revoluble brush 1, the shaft 2 of which is mounted in bearings in the sides of an inclosing case 3. which are cylindrical in shape, are arranged concentrically around the cylindrical brush I and in contacttherewith and are provided with projecting spurs or studs 5, which coact A series of rollers 4, o

wit-h the cylindrical brush in the delinting of the cotton-seeds. The cylindrical brush lis rotated atfa high rate of speed, and the cylindrical rollers 4are rotated at a comparatively low rate of speed, the contacting surfaces of cylindrical brush 1 and rollers 4 moving in the same direction, as indicated by the ar-v rows in Fig. 1. Owing to the dierence in the speed of the cylindrical brush 1 and the rollers 4 the bristles or wires of the brush l in moving past the coacting surfaces of the rollers 4, which retard the seeds in their progress between the coacting surfaces of the brush 1 and rollers 4, delint the cotton-seeds, the lint being carried by the revoluble brush l, and said brush also serving to polish the cotton-seeds, the functions of the rollers 4 being to hold the seeds in contact with the wires of the brush l while the same are being delinted and by the rotation thereof to turn the cotton-seeds during the delinting process, so as to present all surfaces of the cottonseeds in succession to the action of the delinting-wires of the brush.

A series of retaining-bars G are disposed transversely and secured in the casing 3, the said bars bearing upon the surface of the revoluble brush 1 and one of said bars being disposed between each pair of the rollers 4 in the spaces between the proximate sides of said rollers and the surface of the revoluble brush 1. The function of these retainingbars is to keep the cotton-seeds in contact with the revoluble brush 1 as the cotton-seeds are by the rotation of said brush swept from one roller 4 to another in rotation throughout the series of the rollers 4, and to enhance theefficiency of the said retaining-bars the same are provided on opposite sides with brushes 7, the length of which is coeXtensive with that of the said retaining-bars, the said brushes impinging against the sides of the rollers 4 which are opposed to each other, as shown, said brushes serving to prevent the cotton-seeds from being carried by the revolving rollers 4 from the coacting surface of the revoluble brush l. It will be understood that by this construction and combination of devices the cotton-seeds are treated by the coacting brush 1 and rollers 4 successively by each of the series of rollers 4, and as said rollers serve `to impart rotatory motion to the cotton-seeds during the delinting process the machine is efficient in entirely delinting the cotton-seeds and polishing the surfaces thereof.

A feed hopper or chute 8, with which the casin g 3 is provided, conducts the cotton-seed to the surface of the revoluble brush 1 on one side thereof, and below the said hopper or chute is a revoluble cleaning brush and fan 9, the same coacting with the brush 1 and serving to strip the lint from said brush 1. The said combined cleaning brush and fan during the operation of the machine rotates at a high rate of speed and creates a current of air which passes through a discharge-opening 10 in one side of the casing 3, that communicates with a pneumatic conveyer-iiue, the lint by the combined action of centrifugal force generated by the revolution of the brush 9 and the current of air created thereby being detached from the brush 9 and conveyed pneumatically through the conveyor-liuc to the gins or a suitable receptacle. The last of the series of rollers 4 is disposed at some distance below the cleaning and fan brush. 9 and above a seed-conveying iue 1l, and as the delinted cottonseeds emerge from between the coacting surfaces of the revoluble brush 1 and the said roller 4 the seeds drop from the said roller through the said flue 11, as Will be understood. A revoluble and spurred roller 12 is disposed and rotates in the feed hopper or chute 8, the function of the said roller being to agitate the seed-cotton and prevent the 'same from choking the said hopper or chute.

The brushes 1 9 and the yrollers 4 and 12 may be rotated by any suitable means, and I do not limit myself in this particular. In

' Fig. 2 of the drawings the shafts of the rollers 4 are provided at one end with sprocketwheels 13. The shaft of brush 9 is provided with sprocket-wheels 14 15. The shaft of brush 2 is provided with a sprocket-pinion 16,

and an idle sprocket-Wheel 17 is disposed at one side ofthe pinion 16. An endless sprocketchain 18 engages the sprocket-Wheels 13 14, and an endless sprocket-chain 19 connects the sprocket-wheels 15 17 and engages the sprocket-pinion 16. The shaft of the cylindrical brush 1 is provided at the end thereof opposite the pinion 16 with a pulley 20, to which power is appliedv Ibygan endless belt from an engine or other suitable source ofY power, and the said pulley 2O is also connected to a small pulley 21 on the shaft of the cleaning and fan brush 9 by an endless belt '22, as shown in Fig. 3.

Having thus described my invention, I claim-- 1. The combination of a casing having a feed-hopper, a discharge-fine for seeds and a discharge-opening for lint, a revoluble delinting-brush and a series of retaining-rollers, disposed concentrically on said brush, from the feed-hopper to the seed-discharge iiue, and a cleaning-brush, coacting with the said delinting-brush, at a point opposite the lintdischarge opening and between the feed-hopper and seed-discharge iue, said delintingbrush and retaining-rollers coacting to delint the seeds, and convey the delinted seeds to the seed-flue, and said cleaning-brush and delinting-brush coacting to strip the lint from the latter and discharge the same pneumatically through the ,lint-discharge opening, substantially as described.

2. In adelinting-machine, the combination of a revoluble delinting-brush, a series of revoluble retaining peripherally-.spurred rollers disposed around the same, said delintingbrush and retaining-rollers coacting, and the spurs of each of said rollers operatingin planes disposed in the spaces between the spurs of the opposing rollers, and means to rotate said delinting-brush at high speed and said retaining-rollers, at low speed, substantially as described.

3. In a delinting-machine, the combination of the revoluble delinting-brush, the series of retaining-rollers coacting therewith and the retaining-bars disposed between thev opposing sides of said retaining-rollers, and coacting with said delinting-brush, said retainingbars having brushes coacting with said retaining-rollers, for the purpose set forth, substantially as described.

4. In a delinting-machine, the combination with a casing having a feed and a lint-discharge opposite each other, on one side of said casing, of a revoluble delinting-brush in said casing, on one side of said feed and lint-discharge, the motion of which brush is effective in moving seed-cotton in a direction at right angles to the axis of said brush, from said feed to said discharge, the seed-cotton moving with said brush through less than a complete revolution of the latter, and means coacting with said delinting-brush to dispose and retain seed-cotton on the surface of the latter and retard the passage of the seed from Vthe feed to the point of discharge, said brush `carrying the lint while the passage of the seed in process of being delinted is retarded,
